OPINION

The appellant, Marcus L. Wallace, is a state pretrial detainee, currently housed at *138 the Franklin County Jail in Chambers-burg, Pennsylvania. 1 Proceeding pro se, he filed suit in the United States District Court for the Middle District of Pennsylvania, alleging that four named defendants — Officer Corey M. Fegan, Judge Gary Carter, the Chambersburg Police Department, and Franklin County — had violated his constitutional rights in connection with his arrest and prosecution thus far. Having identified at length several deficiencies in the complaint, the presiding Magistrate Judge granted Wallace leave to amend to forestall a recommendation of dismissal. See Order, ECF No. 13. Wallace failed to comply with the Magistrate Judge’s requirements as to the form of his amended complaint, but was granted additional leave to amend to correct this shortcoming. See Order, ECF No. 17.

Wallace then filed the operative amended complaint, ECF No. 19; a discursive document invoking numerous causes of action and multiple claims for relief, the amended complaint appeared primarily to challenge the validity of Wallace’s arrest and the state court’s denial of bail, although it also requested, inter alia, a gag order against the news media to “prohibit access to publication of any information in relation to” the ongoing criminal case. The Magistrate Judge concluded that this complaint fared no better than the previous iterations, recommending dismissal, ECF No. 20; the District Court agreed and, overruling Wallace’s objections, adopted the Report and Recommendation and dismissed the case pursuant to 28 U.S.C. § 1915A. Wallace then filed numerous motions under a variety of captions, all of which were dismissed or denied by the District Court. One such filing, captioned “Petition for Writ of Certiorari” and filed on September 7, 2011, see ECF No. 45, was construed as a notice of appeal.

We have jurisdiction under 28 U.S.C. § 1291, 2 and conduct plenary review of *139 dismissals pursuant to 28 U.S.C. § 1915A. See Tourscher v. McCullough, 184 F.3d 236, 240 (3d Cir. 1999). Pleadings and other submissions by pro se litigants are subject to liberal construction, see Higgs v. Att’y Gen., 655 F.3d 333, 339 (3d Cir. 2011), and we are required to accept the truth of Wallace’s well-pleaded allegations while drawing reasonable inferences in his favor, Capogrosso v. Sup.Ct. of N.J., 588 F.3d 180, 184 (3d Cir. 2009) (per curiam). But a pro se complaint must still “contain sufficient factual matter, accepted as true, to ‘state a claim to relief that is plausible on its face.’ ” Ashcroft v. Iqbal 556 U.S. 662, 129 S.Ct. 1937, 1949, 173 L.Ed.2d 868 (2009) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007)). Motions for reconsideration are reviewed for abuse of discretion. Uni ted States v. Dupree, 617 F.3d 724, 732 (3d Cir. 2010).

We have carefully examined Wallace’s submissions, which — as the District Court observed — are voluminous, numerous, and difficult to parse. From what we are able to glean, however, we agree with the District Court that his allegations do not state a claim upon which relief could be granted.

First, to the extent that Wallace intended to sue the judges who have presided over his criminal case thus far, they are insulated by both absolute and statutory judicial immunity. See Mireles v. Waco, 502 U.S. 9, 9, 112 S.Ct. 286, 116 L.Ed.2d 9 (1991) (per curiam); Azubuko v. Royal 443 F.3d 302, 303-04 (3d Cir. 2006) (per curiam). While “immunity, whether qualified or absolute, is an affirmative defense which must be affirmatively pleaded,” Kennedy v. City of Cleveland, 797 F.2d 297, 300 (6th Cir. 1986), the District Court did not err in raising it sua sponte, as the defect was apparent from the face of the complaint. Ray v. Kertes, 285 F.3d 287, 296 (3d Cir. 2002).

Wallace also alleged that defendant Fegan violated his Fourth Amendment rights in several ways, principally through a supposed “false arrest.” 3 “The proper inquiry in a section 1983 claim based on false arrest or misuse of the criminal process is ... whether the arresting officers had probable cause to believe the person arrested had committed the offense.” Dowling v. City of Phila., 855 F.2d 136, 141 (3d Cir. 1988). “[Wjhere the police lack probable cause to make an arrest, the arrestee has a claim under § 1983 for false imprisonment based on a detention pursuant to that arrest.” Groman v. Twp. of Manalapan, 47 F.3d 628, 636 (3d Cir. 1995). Assuming for the moment that Fe-gan did arrest Wallace-the complaint is not entirely clear on that front — Wallace did not allege that Fegan lacked probable cause to do so. Rather, Wallace asserted that 1) Fegan erred in describing him as a “convicted felon” on the affidavit of probable cause that supported the issuance of an arrest warrant, and that 2) Fegan was acting outside of his jurisdiction when he arrested Wallace. But Wallace has not argued that his status (or lack thereof) as a felon was material to a finding of probable cause in this particular case. See Sherwood v. Mulvihill, 113 F.3d 396, 399 (3d Cir. 1997). While Pennsylvania limits the ability of municipal police to arrest suspects outside of their jurisdiction, see *140 42 Pa. Cons.Stat. Ann. § 8953, the Fourth Amendment is not violated when an otherwise-valid arrest is secured in contravention of a state law regulating the intrastate rules of municipal jurisdiction. 4

To the extent that Wallace alleged that he was injured by a “policy or custom” of Franklin County, see Monell v. Dep’t of Soc. Servs., 436 U.S. 658, 694, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978), we agree with the District Court that Wallace’s bare invocation of “policy” and “custom” was insufficient to state a valid claim. Finally, having examined the many documents that Wallace filed following the District Court’s dismissal of his complaint, we conclude that the District Court did not abuse its discretion by declining to grant relief from judgment. 5

We close by observing that Wallace’s complaint attempted, in part, to attack the in-progress criminal proceedings in state court; for example, he appeared to request criminal discovery and asked the District Court to “bar action” in the criminal case. “[T]he normal thing to do when federal courts are asked to enjoin pending proceedings in state courts is not to issue such injunctions.” Younger v. Harris, 401 U.S. 37, 45, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971); see also Lazaridis v. Wehmer, 591 F.3d 666, 670 n. 4 (3d Cir. 2010) (per curiam) (listing limited exceptions). His seeming challenge to pretrial incarceration seeks a remedy available only in habeas. See Walck v. Edmondson, 472 F.3d 1227, 1235 (10th Cir. 2007).

In sum, because this appeal presents no substantial question, we will summarily affirm the District Court’s judgment. Murray v. Bledsoe, 650 F.3d 246, 248 (3d Cir. 2011) (per curiam); see also 3d Cir. L.A.R. 27.4; I.O.P. 10.6. Wallace’s two requests for the admission of exhibits are denied as in part barred and in part unnecessary. See In re Capital Cities/ABC, Inc. ’s Application for Access to Sealed Transcripts, 913 F.2d 89, 96 (3d Cir. 1990).
